I'd like some more help from the editors in getting 2d layout right
without trying. Here's a mockup of vim with vertical grey bars
delimiting layout:

Does anyone know how to get this effect in vim (or emacs)?
Bonus points if the grey bars are draggable, changing the indenting.
More bonus points for box-based navigation.
